Custom advancements Limit

Can you give me an example? Is this a visual thing? If so, a screenshot would help.

Hey natham,
Now I realised the real problem, but it's still a bug, it's shown in my new report https://bugs.mojang.com/projects/MC/issues/MC-117018?filter=allopenissues
Hope It's useful for you,
Wolfie

NOTE: If screenshots are required, I'll send you ones, but it can be easily tested
